Changes colour with hot or cold temperatures.

Non-Toxic and Harmless: No harsh ingredients or adhesives that lead to damaged nails. The poly nail extension gel is more flexible than acrylic & stronger than hard UV gel & lighter than both, easier to control, which is friendly for beginner.

Long-Lasting Effects: The nail extension gel will last up to about one month or longer with proper Nail Prep (Filing, Buffering, and Cleaning). For the better adhesion and long lasting effects, you can apply nail dehydrator and primer after nail prep. You can refill your nails when the new cuticle area grows, no need to remove them all.
